Supercage - Mobile Cage with Integrated USB-C Hub

Moment SuperCage — turn your phone into a real travel-film rig

The gist: A pro-level phone cage that consolidates mic, monitor, storage, and power into one rig, built for travel creators who've outgrown handheld phone filming.

• Built-in USB-C hub: Connects up to six accessories at once — external mic, headphone monitoring, a full-size SD card, HDMI output, and power, all through the cage base instead of a tangle of dongles.
• Open, modular rig: Continuous NATO rails and an Arca-compatible base let you attach a mic, light, or gimbal handle exactly where you want it.
• Solid build: Reviewers describe the materials as exceptionally well built, with the phone feeling extremely secure once mounted.
• SD card offload: A full-size SD slot means you can shoot and back up footage in remote locations without carrying a laptop.

AppleInsider's review called the SuperCage "the ultimate iPhone filmmaking accessory," praising its build quality while noting the included USB-C cable is stiff enough to make cable management a bit fussy.

Best for: Travel content creators and mobile filmmakers who want a serious, expandable phone rig for the road. Skip it if: you shoot casual social clips — this is overkill (and $199) for anyone not building a real production setup. Runs ~$199 — check the current price before buying.
